For another client the value ft of the portfolio at time t i

For another client, the value f(t) of the portfolio at time t is shown in the graph below. What is the domain of this function?

Solution

Fo domain we see the t values ,( i.e. the values on x axis)

So we can see the values are from 0 to 6 , including 0 and 6 , as they have dark circles

So DOMAIN is [0,6]

Or 0<=x<=6
